井窖式移栽打孔规格及填土封口时间对烤烟生长发育和产质量的影响

Effects of Well-cellar Specification and Filling Time on Growth,Yield and Quality of Flue-cured Tobacco in Well-cellar Transplanting Technology

为筛选出与烤烟井窖式移栽技术配套的打孔规格及填土封口时间,在利川开展井窖式移栽打孔规格及填土封口时间对烤烟生长发育和产质量影响的研究。结果表明,井窖式移栽技术以直径10 cm打孔器打孔,栽后20 d填土半封井窖的处理烤烟农艺性状、经济性状表现较好,烤烟内在化学成分表现较协调。该研究对烤烟井窖式移栽技术的大面积推广应用及烟叶产质量提高提供技术支持。

In order to select the best well-cellar specification and filling time in well-cellar transplanting technology,the experiments of different well-cellar specification and filling time on growth,yield and quality of flue-cured tobacco were carried out in Lichuan.Results showed that the well-cellar specification with a diameter of 10 cm and the filling time at the 20th day after planting were best in well-cellar transplanting technology.In this treatment,the agronomic,economic characters and internal chemical compositions of flue-cured tobacco were better than that in other treatments.Therefore,the results provided technical support for the application of well-cellar transplanting technology and the improvement of flue-cured tobacco yield and quality.
